Before elements (i.e. video, image, sound and links) are added to an Mz3 Title, the parameters should be ckecked and adjusted. Sometimes that’s forgotten. Or it turns out later that parameters should be changed.
Since there is no “multi-selection” and “multi-adjustment” option available yet (that is planed), it has to be done element-by-element.
But a modification can be achieved easilyy. How that is done is shwon in this post.
In Manage Mode, elements can be “searched” (filtered) by element type, language and page.
The resulting table then can be sorted and the element that should be changed can be selected.
Selecting an element is achieved in either clicking into the row with that element, or clicking the element of choice in the “book”.
Once an element is selected, it can be deleted using the “Delete Elements” button, which deletes all selected elements and “remembers” all parameters of the first (or only) one.
After clicking the “Delete Elements” button
You can modify parameters for that element in clicking the “cog” button:
Adding Element back
Hitting the “ADD Element” button will add it back to the list.
Area/Link elements often are invisible and it would be hard to position them without the old reference.
If Video or Image elements remained at the old position, it would look like they had not been deleted; and you probably miss adding them back.
